ABSTRACT:
A mechanism is provided to significantly enhance control over the emission of particulate dust typically generated during operation of a hand-held sander. A suction manifold coupled to any conventional means for providing suction is fitted to the outside of the sander body and communicates through a plurality of connection tubes with a plenum through which particulates generated during sanding are sucked in through apertures in a sanding pad of the sander. Further enhancement of removal of the particulates is obtained by a plurality of grooves in the sanding surface of the sanding pad of the sander, such grooves each having an inside end communicating with a corresponding one of a plurality of apertures through the sanding disk, each groove also having an outside end at an outer periphery of the sanding pad. The provision of supplemental suction through the suction manifold and the use of a grooved sanding disk, as described, significantly reduces particulate emissions and, simultaneously, reduces the suction-induced tendency for the sander to be drawn toward the surface of a workpiece being sanded thereby.
